Device for presetting the tools in a platen press

Abstract

A presetting device for tools used in a press such as a platen press, including by a cradle for slidably receiving each of the tools and being mounted by a turret on a carriage which is shifted along a vertically extending column, which column can be rotated around a vertical axis on a base. The device enables positioning the height of the cradle and also rotating the cradle around both the horizontal and vertical axis to gain access to the tools during the setup operation.

I claim: 
     
       1. A device for presetting tools which are to be used in a platen press, said device including a base, a column, first means for mounting the column on the base on a first axis and for rotating the column on said first axis, a carriage, second means for mounting the carriage on the column and for shifting the carriage along the length of the column, a cradle for receiving the tools, and turret means for mounting the cradle on the carriage and for rotating the cradle on a second axis extending approximately at right angles to the first axis, said turret means including a guiding disk secured to the cradle and having a first group of rollers circumferentially spaced on the circumference of the disk, a ring member being secured to the carriage and having a circular groove for receiving the first group of rollers, a second group of rollers mounted on said guiding disk to extend parallel to the second axis, said second group of rollers being received on a second roller track formed on a frame of the carriage, said guiding disk having an inner toothed track, a pinion gear mounted on an output shaft of a motor and gear reduction unit secured on the carriage with the toothed pinion engaging said tooth track. 
     
     
       2. A device according to claim 1, wherein the column has a pair of side legs, each of said side legs having grooves forming a first track and an inner surface forming a second track, said second means including a first group of rollers mounted on a frame of the carriage and being received in said grooves forming the first track on each leg of the column, a second group of rollers mounted on said frame engaging each of the second tracks on the inner surfaces of the legs, said frame having a fixing piece, said means for shifting including telescopic jacks with output rods, said jacks being secured on the column and having their output rods secured to said fixing piece. 
     
     
       3. A device according to claim 1, wherein the first means for mounting and rotating the column include a toothed wheel having a projection received in a bushing on the base, a roller bearing positioned between said toothed wheel and base, said base having a fixed part mounting rollers engaging an upper surface of the toothed wheel to maintain the column on said first axis, a drive motor and reduction gear unit being mounted on said fixed part and having a pinion gear on the output shaft of the unit, said pinion gear engaging the tooth wheel for rotating the toothed wheel and column on the first axis of said bushing. 
     
     
       4. A device according to claim 3, wherein the column has a pair of side legs, each of said side legs having grooves forming a first track and an inner surface forming a second track, said second means including a first group of rollers mounted on a frame of the carriage and being received in said grooves forming the first track on each leg of the column, a second group of rollers mounted on said frame engaging each of the second tracks on the inner surfaces of the legs, said frame having a fixing piece, said means for shifting including telescopic jacks with output rods, said jacks being secured on the column and having their output rods secured to said fixing piece. 
     
     
       5. A device for presetting tools which are to be used in a platen press, said device including a base, a column, first means for mounting the column on the base on a first axis and for rotating the column on said first axis, a carriage, second means for mounting the carriage on the column and for shifting the carriage along the length of the column, a cradle for receiving the tools, and turret means for mounting the cradle on the carriage and for rotating the cradle on a second axis extending approximately at right angles to the first axis, said column having a pair of side legs, each of said side legs having grooves forming a first track and an inner surface forming a second track, said second means including a first group of rollers mounted on a frame of the carriage and being received in said grooves forming the first track on each leg of the column, a second group of rollers mounted on said frame engaging each of the second tracks on the inner surfaces of the legs, said frame having a fixing piece, said means for shifting including telescopic jacks with output rods, said jacks being secured on the column and having their output rods secured to said fixing piece. 
     
     
       6. A device according to claim 5, wherein the first means for mounting and rotating the column include a toothed wheel having a projection received in a bushing on the base, a roller bearing positioned between said toothed wheel and base, said base having a fixed part mounting rollers engaging an upper surface of the toothed wheel to maintain the column on said first axis, a drive motor and reduction gear unit being mounted on said fixed part and having a pinion gear on the output shaft of the unit, said pinion gear engaging the toothed wheel for rotating the toothed wheel and column on the first axis of said bushing. 
     
     
       7. A device for presetting tools which are to be used in a platen press, said device including a base, a column, first means for mounting the column on the base on a first axis and for rotating the column on said first axis, a carriage, second means for mounting the carriage on the column and for shifting the carriage along the length of the column, a cradle for receiving the tools, and turret means for mounting the cradle on the carriage and for rotating the cradle on a second axis extending approximately at right angles to the first axis, the first means for mounting and rotating the column including a toothed wheel having a projection received in a bushing on the base, a roller bearing being positioned between said toothed wheel and base, said base having a fixed part mounting rollers engaging an upper surface of the toothed wheel to maintain the column on said first axis, a drive motor and reduction gear unit being mounted on said fixed part and having a pinion gear on the output shaft of the unit, said pinion gear engaging the toothed wheel for rotating the toothed wheel and column on the first axis of said bushing.
